NO ELECTRICAL POWER TO CAB!! NEED HELP ASAP!!

[Sno-Mow]

Lowered the cab today from doing HG job, got everything hooked up and fluids filled...hit the key...NOTHING!!!

After further investigation, found there's no power to the fuses. Batteries checked out good, double, then triple checked all wiring harnesses, checked and cleaned all battery connections including battery to frame grounds, checked all other grounds...all good.

WHAT AM I MISSING?? They're saying snow on Sunday night and need to get piggy running before then and would like to have a couple hundred miles on before I hook up the plow.

I'm not familiar with the wiring on our trucks. But check your fusible links. I have no idea where they might be located. But they are basically a piece of wire that acts as a fuse. They will be inside the wiring harness somewhere.

Checked them. With probe on battery ground theres power on both sides of the links. They're on the passenger side battery on the small cable going into the engine harness.

Would the PCM relay cause this?
